Prince William and Catherine Middleton, the Duke and Duchess of Cambridge, have released the photos of their children Prince George and Princess Charlotte together. The littlest royals’ adorable pictures were shot by their mother in mid-May at the family’s country home in Anmer Hall.

Kensington Palace, the official London residence of William and Kate, has shared the “very special” photos on its Twitter and Instagram accounts on Sunday.
